Document Type and Number:
WIPO Patent Application WO/2021/006673
Kind Code:
A1
Abstract:
A liquid lens control device according to an embodiment comprises: a liquid lens including a first liquid and a second liquid which form an interface with a first electrode and a second electrode; a lens driving unit which controls the interface by applying a voltage to the first electrode and the second electrode, and includes a plurality of switching elements; a temperature sensing unit which senses the temperature of the liquid lens; and a control unit which controls the lens driving unit such that the interface forms a target interface. The control unit maintains the switching states of the plurality of switching elements of the lens driving unit during a temperature sensing period in which the temperature sensing unit operates.
